Blink Behaviour, Pupil Diameter, and Technical Performance in Elite Male Table Tennis Players: A Wearable Eye-Tracking Study
Abstract
El tenis de mesa requiere un procesamiento continuo de información visual y un control visuomotor preciso. Este estudio observacional transversal analizó variables relacionadas con el parpadeo y el diámetro pupilar durante una prueba estandarizada de rendimiento en 17 jugadores masculinos de élite. Los participantes realizaron 50 golpes de topspin de derecha analizados mediante tecnología portátil de seguimiento ocular. La frecuencia de parpadeo mostró la asociación positiva más fuerte con la precisión de los golpes, aunque esta relación dejó de ser estadísticamente significativa tras la corrección por comparaciones múltiples. No se observaron asociaciones significativas entre las variables de parpadeo y la velocidad de la pelota, ni entre el diámetro pupilar y las medidas de rendimiento. Los resultados deben considerarse exploratorios y requieren confirmación en muestras mayores.
Table tennis is a fast interceptive sport that requires continuous visual information processing and precise visuomotor control. This observational cross-sectional study analysed blink-related and pupil-related variables during a standardised table tennis stroke-performance test in 17 elite male players. Participants completed 50 analysed forehand topspin strokes while ocular behaviour and technical performance were recorded. Blink frequency showed the strongest positive association with stroke accuracy, although this association did not remain statistically significant after false discovery rate correction. No significant associations were observed between blink-related variables and ball velocity. Pupil-diameter variables were not significantly associated with either stroke accuracy or ball velocity. These findings suggest that blink-related measures may provide complementary information about technical accuracy, although the results remain exploratory and require confirmation in larger samples using time-resolved analyses.
